What made him feel a little different was that.

The attribute panel of the continuous-fire crossbow in his hand has F-level props written on it.

But the strong light flashlight did not write any props of what level it was.

Is it because the strong light flashlight cannot be held on the table, and it has no level?

Shaking his head and throwing away the distracting thoughts in his mind.

He narrowed his eyes, and his face calmly raised a strong crossbow with one hand and a flashlight with the other, slowly fumbled forward.

This passage is no different from the passage behind him.

The same structure, the same silence.

It took about a few hundred meters to walk.

It's over again, this time to the right.

But this time the distance was relatively long, and after walking for about a thousand meters.

There is no way ahead again.

But this time it's a little different.

Chen Fa swallowed his saliva and stared at the explosion-proof door that was about 30 centimeters thick in front of him, and murmured: "Have you picked up the treasure?"

I saw a circular hole in front of me, a circular explosion-proof door about 30 centimeters thick, which was hidden.

After pushing it away with force.

After thinking for a moment, he held up the flashlight and drilled in.

The first thing that caught my eye inside was a space of about two or three hundred square meters, where you could see the broken light bulbs on the roof and the tables and chairs lying on the side.

It looks extremely messy.

And he also saw that there was a valve-like thing behind the explosion-proof door on the inside, which also said that the door was closed and twisted to the right.

“Close the door manually?”

A trace of light flashed in Chen Fa's eyes, and then he couldn't help but grin.

He is familiar with this place.

When he was on Blue Star, he had watched many adventure shows. One of the crooked and cruel people named Radish Head left a deep impression on him. Isn’t this place just an air-raid shelter?

The circular explosion-proof door behind us is manual. In an era when the power system is completely destroyed, such a manual explosion-proof door will greatly increase the sense of security brought by people.

But he did not close the door as soon as possible. After all, the inside of the air-raid shelter has not been checked yet. If there is a monster or something, it will really cut off his back.

but...

He licked the corner of his mouth, his eyes flashed with anticipation, took out the disposable shelter drawing from his backpack and pointed it at the space in front of him.

Suddenly a prompt panel popped up in front of you.

【Whether to set the air raid shelter in front of you as your shelter?】

【The air raid shelter is in a broken state.】

[If you need to set this air raid shelter as your shelter, you need to add iron ore × 1200 and wood × 1100.]

"It's true!"

Chen Fa's expression couldn't help but become excited. If he had an air raid shelter as a shelter in this dangerous world, his sense of security would definitely be greatly improved.

The walls cast by concrete and steel bars, and these 30 cm thick explosion-proof doors, are definitely more secure than the newsstand in the middle of the street.

But why does the office building next to the street need to be replenished with iron ore × 5000, and the wood even more need × 8000.

However, this safer air raid shelter only requires so little material.

He lowered his head and thought for a moment, and then he understood what was going on.

It should be that the office building next to the street was too damaged, so more materials were needed if it was set up as a shelter, and this air raid shelter obviously had no obvious damage.

After thinking about this.

After Chen Fa breathed a little relieved, he did not let go of his vigilance.

Instead, he held the flashlight in front of him with his left hand, and held the continuous force crossbow in his right hand, put his right wrist on his left hand arm, forming the simplest single-soldier exploration posture, and began to grop.

...

About half an hour.

After Chen Fa took a breath, he gently wiped the cold sweat from his forehead, and he had already explored it all.

There were no human figures, and no monsters.

Sinking into extreme silence.

This extreme silence made him feel a little uncomfortable.

There are three outlets, all of which are manual round explosion-proof doors.

One of the exits is on the wall. After drilling into the hole, you will see a deep well above your head. There is a row of steel bars on the wall to form a ladder embedded in the well wall.

At the top is a grid made of steel bars into the shape of a 'well'.

It should be used for air circulation. At this time, all the power systems in this air raid shelter were destroyed, and ventilation can only be achieved through this channel.

Emergency moments can also be used as an emergency retreat channel.

In addition to the space he came in just now, there were seven rooms, each with its own uses. He did not check carefully, but only checked whether some horns were hidden or monsters.

At this time, the two explosion-proof doors had been completely closed by him, and he returned to the explosion-proof door he had just entered.

After about two minutes, the explosion-proof door was closed.

He let out a light breath, stared at the dust on the ground and identified it carefully, and confirmed that when he was exploring this air-raid shelter, no one else stepped in, and he felt relieved.

However, he was still a little uncertain.

What if someone follows you?

So he spent ten minutes patrolling the rooms one by one again.

It is confirmed that he is the only one in the entire air raid shelter.

After all the three explosion-proof doors were closed, he took out the disposable shelter drawing from his arms, and hesitated no longer, aiming it at the space in front of him.

【Confirm construction.】

Next second—

[Please add materials, iron ore × 1200, wood × 1100.]

Chen Fa grinned and looked at his own materials.

【Wood × 997, iron ore × 983, soil × 0.】

Not much worse.

Next is-

Chen Fa rolled up his sleeves and looked at the iron table and wooden chairs beside him, his eyes flashing with enthusiasm.

I have to start working hard.

At this time, there was still an hour and a half before dark, so there was not much time left for him.

...

One hour later.

Chen Fa held the hoe panting and couldn't help but curse: "The physical fitness is still a bit poor, and I have to pick up and exercise again."

But then he looked at his personal information and nodded with satisfaction and grinned.

【Iron ore × 1256, wood × 1101, soil × 0.】

There is already enough materials for building this shelter.

No hesitation.

Confirm construction.

Next second—

I saw this disposable protection drawing suddenly turned into white light and exploded in front of him, melting into the surrounding walls like a meteor, and the materials on his personal panel were also decreasing at an extremely rapid pace.

About a few seconds later.

[Ding, congratulations to the player Chen Fa on successfully establishing a shelter!]

[Ding, congratulations to the shelter established by player Chen Fa, with a defense of 1387 and successfully topped the shelter ranking list!]

Chen Fa, who was about to check the shelter rankings, suddenly found that the World Chat Channel in the lower left corner was flashing.

It turned out that at some point, 100,000 shelters had been established around the world, but there was no prompt.

Think about it, too.

With so many people around the world, it is not too easy to build a hundred thousand shelters.
Chapter completed!
